B. HTTP ■
C. SMTP
D. POP3
Correct Answer: B. HTTP
Rationale: Web GIS commonly uses HTTP/HTTPS to request and transfer map, feature, and service resources.
2. Which ArcGIS component is primarily used to publish and manage GIS web services?
A. ArcGIS Server ■
B. ArcGIS Pro Layout
C. ArcGIS Survey123 only
D. ArcGIS Field Maps only
Correct Answer: A. ArcGIS Server

3. What does REST stand for in the context of web services?
A. Remote Execution Service Transfer
B. Representational State Transfer ■
C. Raster Encoding Service Technology
D. Resource Exchange Spatial Transfer
Correct Answer: B. Representational State Transfer
Rationale: REST is an architectural style based on resources, representations, and stateless HTTP interactions.
4. Which OGC service is designed primarily to deliver rendered map images?
A. WMS ■
B. WFS
C. WCS
D. CSW
Correct Answer: A. WMS
Rationale: OGC Web Map Service (WMS) returns map images generated from geographic data.
5. Which OGC service is designed to provide vector features and their attributes?
A. WMS
B. WFS ■
C. WCS
D. WMTS
Correct Answer: B. WFS
Rationale: Web Feature Service (WFS) provides access to vector geographic features and their attributes.
6. Which OGC service is intended for coverage/raster data access?
A. WCS ■
B. WFS
, C. WMS
D. CSW
Correct Answer: A. WCS
Rationale: Web Coverage Service (WCS) is designed for multidimensional or coverage data such as raster
datasets.
7. What is the main purpose of a GIS web map client?
A. To compile a desktop operating system
B. To visualize and interact with geographic services in a browser or app ■
C. To replace all databases
D. To manufacture GPS receivers
Correct Answer: B. To visualize and interact with geographic services in a browser or app
Rationale: A web map client consumes web services and provides interactive visualization and tools.
8. Which HTTP method is normally used for retrieving a resource in REST?
A. GET ■
B. DELETE
C. PATCH
D. TRACE
Correct Answer: A. GET
Rationale: GET is conventionally used to retrieve a representation of a resource.
9. What does statelessness mean in REST?
A. The server stores every client's UI state between requests
B. Each request contains the information needed to process it ■
C. No data can ever be stored
D. Clients cannot use authentication
Correct Answer: B. Each request contains the information needed to process it
Rationale: A stateless service does not rely on stored client-session state between requests.
10. Which technology is commonly used to represent structured geographic data in web
applications?
A. GeoJSON ■
B. MP3
C. DOCX
D. BMP only
Correct Answer: A. GeoJSON
Rationale: GeoJSON is a JSON-based format for representing geographic features and their properties.
11. What is a tile cache used for in Web GIS?
A. To pre-render map tiles for faster display ■
B. To encrypt all passwords
C. To replace coordinate systems
D. To store email attachments
Correct Answer: A. To pre-render map tiles for faster display
Rationale: Cached tiles reduce the need to render the same map repeatedly, improving performance.
